Things are going well with the Atmega128 and AD9851 DDS. PCB’s are ready. 90% of the Bascom-AVR-code is finished. We made a lookup-table, starting with frequency from 12.6 Mhz - 40.6 Mhz in steps from 500 Khz. With a single button you can ‘walk’ through this table. There are eight user defined frequencies and they can be configured also with just one button. When powered up a dynamic menu appears. It automatic scrolls through all items and when selected, it automatic scrolls through all options. The Bascom-AVR code for this menu will be our entry into the www.mcselec.com contest for the ZL8 and ZL10 development boards.

We have been busy, for a week, with an Atmega128 and an AD9851 DDS.

We got it working, a signalgenerator 12.6 - 40.6 Mhz in steps of 500 Khz. With a 2 x 20 LCD display, two buttons, with a very nice menu to choose the frequencies.
